Allied Machine 433T-0116 Spade Drill Insert 1-1/2 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 433T-0116 is a spade drill insert designed for high-performance drilling applications in steel, cast iron, and non-ferrous metals. Part of the GEN2 T-A series, this insert measures 1-1/2 inches in diameter and seats in a size 3 holder. It is constructed from M4-grade high speed steel with a TiN (titanium nitride) PVD coating that extends cutting life and reduces friction at the cutting edge. The 132-degree point angle is suited to a wide range of general-purpose drilling operations. Machinists and tooling technicians working in production or job-shop environments are the primary users of this insert.

This insert is intended for use with compatible GEN2 T-A series seat size 3 spade drill holders. It handles primary workpiece materials classified under steel (P), cast iron (K), and non-ferrous metal (N) designations, making it a versatile choice for multi-material production drilling setups. It is commonly used in CNC machining centers, manual mills, and drill presses where consistent hole quality and insert replaceability are priorities. The insert is sold individually as a single-piece unit.

Designed for use with GEN2 T-A series spade drill holders requiring a seat size 3 insert. Compatible workpiece materials include steel, cast iron, and non-ferrous metals.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician. Power down and lock out the machine before replacing or inspecting the insert. Inspect the holder seat for chips or wear before installing a new insert, as a damaged seat can cause runout or premature insert failure. Follow the holder manufacturer torque specifications for the clamping screw — do not overtighten.
